Summary: French performance and respect for equipment

The Burly 4021B pads are the result of a unique collaboration between French engineers specialized in railway, automotive and motorcycle brake linings, and top-level riders. This expertise guarantees remarkable or even exceptional longevity while preserving the integrity of your rotors. Manufactured in France with a NoNitech process (without nickel, a toxic ore), they are delivered in 100% recyclable packaging. Their exclusive formulation ensures high braking power in dry and wet conditions, with excellent initial bite and exemplary progressiveness.

Technical strengths of the Burly compound

• Exceptional longevity: The high-performance sintered metal formula offers a lifespan superior to original pads, reducing replacement frequency and maintenance costs.
• Rotor respect: The balanced composition preserves your brake rotors from premature wear, extending their lifespan and maintaining optimal performance.
• Power and progressiveness: Excellent initial bite with remarkable proportionality between lever effort and delivered power, for precise modulation in all circumstances.
• Thermal performance: Very good high-temperature performance, essential for long technical descents and repeated braking in Enduro.
• Pre-bedded: Operational immediately after installation, without tedious bedding-in phase, to instantly enjoy maximum power.
• Responsible French manufacturing: Produced in France using a NoNitech process eliminating nickel, toxic to humans and the environment, with 100% recyclable packaging.

Extended multi-brand compatibility

These 4021B pads fit a vast range of MTB disc brakes. Shimano compatible: Deore BR-M515, BR-M525 (meca 01 and hydro 03-04), BR-M355, BR-M375, BR-M395/M396, BR-M415/M416/M416A, BR-M445/M446/M447, BR-M465, BR-M475, BR-M485/M486, BR-M495, BR-M575, BR-M596, BR-M4050, BR-T615, BR-T675, BR-MT500, as well as Nexave BR-C501/C601/C607 and Tourney BR-TX805.

Giant compatible: MPH, MPH Root and Route. Promax compatible: DSK 909 (Q6). This versatility makes it a wise choice for equipping several bikes with a single pad model.

XC - AM - Enduro use and E-Bike optimization

The Burly compound is specifically developed for Cross-Country, All-Mountain and Enduro disciplines, where long-term reliability and precise modulation are paramount. Its excellent thermal resistance and progressiveness also make it an ideal choice for electric-assist bikes (E-Bike), which place greater demands on the braking system due to weight and higher speeds. The formula guarantees consistent and safe braking, even after kilometers of technical trails. Whether you're linking singles on a ride or attacking committed descents, these pads provide the confidence needed to push your limits.

The Brake Authority DNA: Performance and Respect

Founded in 2008 by Fabien Barel, multiple DH world champion and EWS winner, in association with Fred Glo and Laurent Cornec of Tribe Sport Group, Brake Authority embodies two fundamental values: Performance and Respect. Each pad is the result of intensive field testing conducted by professional riders and development in partnership with a renowned French manufacturer of railway, automotive and motorcycle brake linings. This expertise guarantees products with an unmatched level of performance, designed to withstand the most extreme conditions. Respect is demonstrated through environmental commitment: elimination of nickel (NoNitech), French manufacturing, recyclable packaging and a used pad recycling program. Today, the team continues to innovate under the leadership of Levy Batista, former French Motocross champion turned MTB enduro rider, engineer and product testing manager.
